Abstract: Mitochondrial fatty acid Ξ²-oxidation (FAO) is an essential component of energy production and homeostasis in humans. During periods of limited glucose supply, FAO in the liver provides energy for hepatic function and the acetyl-CoA substrate needed for hepatocytes to synthesize and release ketone bodies into circulation. Ketone bodies provide an alternative energy substrate for peripheral tissues when glucose supply is limited. Other tissues such as skeletal and cardiac muscle rely on FAO for energy production. The oxidation of fatty acids can provide up to 80% of the energy requirements for cardiac and skeletal muscle while sparing glucose for use by the brain and CNS during moderate exercise, fasting, or illness. Disorders in the ability to use fatty acids for energy production manifest during periods of increased energy demands or reduced caloric intake.

Correction: FADH2 and Complex II

Ambiguity alert.png
FADH2 is shown as the substrate feeding electrons into Complex II (CII). This is wrong and requires correction - for details see Gnaiger (2024).
